Just to clarify...your kicker uses ONLY a motor and gearbox to provide the impulse? No tubing or springs???

We don't use springs or anything with elastic energy conservation. I don't understood exactly what is "tubbing", but we calculate the force for the kicker based in the centripetal acceleration!!

By "tubing" he was referring to the surgical tubing provided in the kit (stretched out to provide elastic energy). Your answer shows that you're not using it.

So did you just program a limiter onto the motor? Does it reverse, or is the motor somehow mechanically pulled away from the kicker?
This looks really effective! good job.

We are using two limit's sensors (in order to provide for us two positions: the armed position for the kick and the position after of the kick. Note: the same sensor which detect that the ball was been kicked will detect if there is some ball for kick).

So we keep our kick armed within FRAME PERIMETER and when the driver to press the button, the CIM motor turns forward. After kick, CIM motor turns reverse and keep armed position.

By PWM variation we can change how far the ball goes!

Note: we'll adapt some mechanism to guarantee that pendulum will keep the armed position when the robot move yourself.
